BACKGROUND

The present invention relates generally to an article of footwear, and in particular to a customization kit for an article of footwear.

Tuhkru et al. (U.S. patent application publication number 2006/0049181) teaches a perfect fit system for leather shoes. Tuhkru teaches a system that uses two heating bags filled with sea salt. Tuhkru teaches microwaving the bags for several minutes and then placing the bags inside of a pair of shoes. The shoes can be placed in a heat conservation bag. The process is completed by cooling the heated shoes on the foot.

Laberge (U.S. Pat. No. 4,964,229) teaches a method and apparatus for vacuum molding multi-layer footwear. Laberge teaches multi-layer footwear formed of laminated layers of material. The layers are capable of being heating to a degree at which the footwear, when placed in a vacuum bag or compression chamber, is molded to adopt the shape of the foot inside the footwear. The footwear is heated to the point where the synthetic components of the layers of material are flexible under thermoforming conditions.

Simonsen (U.S. Pat. No. 3,848,287) teaches a method and apparatus for custom molding boots and shoes. Simonsen teaches a boot or shoe formed of a thermoplastic material. To better conform it to the wearer's foot, the wearer puts his foot within the boot and places it within a bag of a plastic material having a melting temperature higher than the molding temperature of the boot. A vacuum line is also placed within the bag and the top of the bag is sealed around the user's leg.

The related art lacks provisions for allowing a user to easily customize an article of footwear. There is a need for a design that addresses this problem of the related art.

DETAILED DESCRIPTION

FIGS. 1 through 5 illustrate an embodiment of footwear customization kit 100, also referred hereafter as kit 100. Footwear customization kit 100 can be used with any type of footwear. In addition, the principles discussed throughout this detailed description may not be limited in use to footwear. Similar principles could be applied to customization kits for various different types of apparel as well.

In some embodiments, footwear customization kit 100 may used by a customer at home. For example, in some cases, a customer could purchase footwear customization kit 100 at a retail location and bring kit 100 home. In other cases, kit 100 may be shipped to an address associated with the customer. In other embodiments, footwear customization kit 100 could be used at any other location, such as a retail store or a kiosk.

Kit 100 may include container 102, which is shown in a closed position in FIG. 1. Container 102 can be any type of container configured to store at least one article of footwear. In some cases, container 102 may be a box. In an exemplary embodiment, container 102 may be a shoebox that is configured to store footwear. In particular, container 102 may have a generally rectangular shape and can include lower portion 104 and lid 106.

Referring to FIGS. 2 through 5, kit 100 can include various different components for customizing one or more articles of footwear. In one embodiment, kit 100 can include pair of footwear 200. Pair of footwear 200 may further comprise first article of footwear 202 and second article of footwear 204. Generally, articles of footwear associated with kit 100 can be any type of footwear. For clarity, the following detailed description discusses articles of footwear in the form of sports shoes, but it should be noted that in other embodiments any other type of footwear could be used including, but not limited to: hiking boots, soccer shoes, football shoes, sneakers, rugby shoes, basketball shoes, baseball shoes as well as other kinds of shoes. Articles of footwear associated with kit 100 may also take the form of any non-athletic shoe, including, but not limited to, dress shoes, loafers, sandals, and boots. An individual skilled in the relevant art will appreciate, therefore, that the concepts disclosed herein apply to a wide variety of footwear styles, in addition to the specific style discussed in the following material and depicted in the accompanying figures.

First article of footwear 202 and second article of footwear 204 may be oriented for a left foot and a right foot, respectively. For purposes of clarity, the following detailed description discusses first article of footwear 202, but it will be understood that each of the features discussed for first article of footwear 202 could also apply to second article of footwear 204. Furthermore, first article of footwear 202 may also be referred to as article 202 throughout the remainder of this detailed description.

Referring to FIG. 4, for purposes of reference, article 202 may be divided into forefoot portion 10, midfoot portion 12 and heel portion 14. Forefoot portion 10 may be generally associated with the toes and joints connecting the metatarsals with the phalanges. Midfoot portion 12 may be generally associated with the arch of a foot. Likewise, heel portion 14 may be generally associated with the heel of a foot, including the calcaneus bone. In addition, article 202 may include lateral side 16 and medial side 18. In particular, lateral side 16 and medial side 18 may be opposing sides of article 202. Furthermore, both lateral side 16 and medial side 18 may extend through forefoot portion 10, midfoot portion 12 and heel portion 14.

It will be understood that forefoot portion 10, midfoot portion 12 and heel portion 14 are only intended for purposes of description and are not intended to demarcate precise regions of article 202. Likewise, lateral side 16 and medial side 18 are intended to represent generally two sides of an article, rather than precisely demarcating article 202 into two halves. In addition, forefoot portion 10, midfoot portion 12 and heel portion 14, as well as lateral side 16 and medial side 18, can also be applied to individual components of an article, such as a sole structure and/or an upper.

For consistency and convenience, directional adjectives are employed throughout this detailed description corresponding to the illustrated embodiments. The term “longitudinal” as used throughout this detailed description and in the claims refers to a direction extending a length or major axis of an article. In some cases, the longitudinal direction may extend from a forefoot portion to a heel portion of the article. Also, the term “lateral” as used throughout this detailed description and in the claims refers to a direction extending a width or minor axis of an article. In other words, the lateral direction may extend between a medial side and a lateral side of an article. Furthermore, the term “vertical” as used throughout this detailed description and in the claims refers to a direction generally perpendicular to a lateral and longitudinal direction. For example, in cases where an article is planted flat on a ground surface, the vertical direction may extend from the ground surface upward. In addition, the term “proximal” refers to a portion of a footwear component that is closer to a portion of a foot when an article of footwear is worn. Likewise, the term “distal” refers to a portion of a footwear component that is further from a portion of a foot when an article of footwear is worn. It will be understood that each of these directional adjectives may be applied to individual components of an article, such as an upper and/or a sole structure.

Referring to FIGS. 2 through 4, article 202 can include upper 222. Generally, upper 222 may be any type of upper. In particular, upper 222 may have any design, shape, size and/or color. For example, in embodiments where article 202 is a basketball shoe, upper 222 could be a high top upper that is shaped to provide high support on an ankle. In embodiments where article 202 is a running shoe, upper 222 could be a low top upper.

Article 202 can include sole structure 224. In some embodiments, sole structure 224 may be configured to provide traction for article 202. In addition to providing traction, sole structure 224 may attenuate ground reaction forces when compressed between the foot and the ground during walking, running or other ambulatory activities. The configuration of sole structure 224 may vary significantly in different embodiments to include a variety of conventional or non-conventional structures. In some cases, the configuration of sole structure 224 can be configured according to one or more types of ground surfaces on which sole structure 224 may be used. Examples of ground surfaces include, but are not limited to: natural turf, synthetic turf, dirt, as well as other surfaces.

Sole structure 224 extends between the foot and the ground when article 202 is worn. In different embodiments, sole structure 224 may include different components. For example, sole structure 224 may include an outsole, a midsole, and/or an insole. In some cases, one or more of these components may be optional.

Article 202 can be configured with one or more customizable portions. The term “customizable portion” as used throughout this detailed description and in the claims refers to a portion with characteristics that can be customized. Examples of such characteristics include, but are not limited to, size, shape, material properties (such as rigidity and/or flexibility) as well as other properties. In an exemplary embodiment, a customizable portion may a portion with a size and/or shape that can be adjusted. In addition, in some cases, the material properties of a customizable portion could also be adjusted.

The characteristics of customizable portions can be varied in different ways. In some embodiments, a customizable portion can be varied through a curing process. In other words, the customizable portion may be heated above a predetermined temperature and modified before cooling the customizable portion so that the modifications are retained. In other embodiments, the characteristics of customizable portions can be varied through the use of pressure, chemical additives or other known methods of changing the characteristics of material including the size, shape, rigidity, flexibility and/or other properties. In still other embodiments, a combination of heat, pressure and/or chemicals could be used to modify the customizable portion.

Generally, article 202 can comprise one or more customizable portions. In some embodiments, sole structure 224 may be associated with one or more customizable portions. In other embodiments, upper 222 may be associated with one or more customizable portions. In some cases, a customizable portion may be associated with forefoot portion 10, midfoot portion 12 and/or heel portion 14 of upper 222. In other cases, a customizable portion may be associated with any combination of different portions of upper 222. In an exemplary embodiment, upper 222 may include customizable portion 230. In particular, customizable portion 230 may extend through a substantial majority of upper 222. In some cases, customizable portion 230 may coincide with upper 222. Using this arrangement, upper 222 may be custom shaped to the specific geometry of the foot of a user to enhance comfort and fit.

In different embodiments, customizable portions can be made from any known materials or combination of materials. Examples of materials that may be used include, but are not limited to: any kind of thermoset polymers, thermoplastics, thermoset resins (such as epoxy, vinlyester and polyster), synthetic leathers including poromeric leathers and lorica, as well as any other kinds of materials with customizable characteristics. In an exemplary embodiment, a customizable portion may be constructed as a synthetic leather comprising two polymer layers that sandwich a canvas sheet. Moreover, a glue used to bond the polymer layers to the canvas may be configured with a relatively low melting point. When steamed, this glue can stretch or shrink to accommodate a customized shape. Although the current embodiment discusses a three-layered construction, other customizable portions could incorporate any other number of layers including a single layer construction.

In order to modify customizable portion 230, article 202 may be heated above a predetermined temperature. For example, in embodiments where a customizable portion may transition between a crystalline phase and a liquid like phase, the predetermined temperature can be a glass transition temperature. In some cases, the glass transition temperature is useful in characterizing amorphous solids such as plastics or similar materials that may not have a true melting point. However, in other cases, the predetermined temperature can be some other temperature at which a customizable portion may become substantially more deformable. In some cases, article 202 may be placed in an oven. In other cases, article 202 may be heated using steam. In an exemplary embodiment, article 202 may be heated in any steam environment. A steam environment can be created in different ways. In some cases, a steam environment can be created using a pot with water that may be boiled to create steam. In other cases, any other devices or mechanisms for creating steam can be used. By selecting materials for a customizable portion that become substantially more deformable at temperatures less than or equal to the temperature of steam, a customizable portion can be activated by applying steam to an article of footwear.

A footwear customization kit can include provisions to facilitate steaming an article of footwear for modifying one or more customizable portions. In one embodiment, footwear customization kit 100 can include stand 302 for holding article 202 above or within a steaming device. Stand 302 can include base portion 304 and footwear engaging portion 306. Base portion 304 may be configured to engage a portion of a steaming device that is used for creating a steam environment. For example, in embodiments where the steaming device is a pot, base portion 304 may engage a bottom interior surface of the pot. In some cases, footwear engaging portion 306 may extend generally perpendicularly from base portion 306.

Referring now to FIG. 4, in different embodiments, the shape of base portion 304 and/or footwear engaging portion 306 may vary. Base portion 304 may have an approximately two dimensional shape. Examples of different shapes for base portion 304 include, but are not limited to, rounded shapes, rectangular shapes, polygonal shapes, regular shapes, irregular shapes as well as any other kind of shapes. In the current embodiment, base portion 304 may have an approximately rectangular shape. In addition, footwear engaging portion 306 may have an approximately two dimensional shape that extends from base potion 304 in a perpendicular manner. Examples of different shapes for footwear engaging portion 306 include, but are not limited to any of the shapes discussed above for base portion 304. In an exemplary embodiment, footwear engaging portion 306 may have an irregular shape.

In some cases, footwear engaging portion 306 can comprise distinct portions that are associated with different portions of an article of footwear. In some embodiments, footwear engaging portion 306 may include lower portion 310 and upper portion 312. Lower portion 310 may be disposed adjacent to base portion 304. In some cases, lower portion 310 may have a substantially larger width than upper portion 312. In particular, upper portion 312 may be narrow enough to insert into a throat opening of an article. In contrast, lower portion 310 may be substantially wider than upper portion 312. In particular, lower portion 310 may be wider than the throat opening of an upper. In some cases, footwear engaging portion 306 can also include shoulder portion 314 that extends between lower portion 310 and upper portion 312. In one embodiment, the width of shoulder portion 314 may vary between lower portion 310 and upper portion 312. With this arrangement, the throat opening of an article may rest against shoulder portion 314 to help hold article 202 in place and in a generally upright position.

Stand 302 may be associated with width W1, length L1 and height H1. In particular, the dimensions of base portion 304 may be characterized width W1 and length L1. In addition, the dimensions of footwear engaging portion 306 may be characterized by height H1 and width W1. In some cases, lower portion 310 may be associated with width W1 and upper portion 312 may be associated with width W2 that substantially less than width W1.

In different embodiments, the dimensions of stand 302 can vary. In some cases, width W1 of stand 302 and width W2 of upper portion 312 can be varied in order to accommodate articles of varying sizes. In some cases, width W2 of upper portion 312 may be substantially smaller than width W4 throat opening 250 of article 202. This allows upper portion 312 to insert into forefoot portion 10 of article 202 through throat opening 250. In addition, in some cases, width W1 of lower portion 310 may be substantially larger than width W4 of throat opening 250 of article 202. This arrangement may prevent article 202 from sliding too far down footwear engaging portion 306.

In addition, in some cases, the values of width W1 and length L1 may be selected so that base 304 is large enough to maintain an article of footwear in an upright position. In other words, length L1 and width W1 may be chosen to prevent footwear engaging portion 306 and an article of footwear disposed on footwear engaging portion 306 from tipping over. Additionally, length L1 and with W1 may be selected so that base portion 304 fits within a portion of a steaming device. For example, in embodiments where the steaming device is a pot with a predetermined diameter, length L1 and width W1 may selected to fit within the diameter of the pot.

In some embodiments, stand 302 may be configured to fit within container 102. In other words, the dimensions of stand 302 may be selected to allow stand 302 to be packed within container 102. In particular, the length, width and height of stand 302 may be selected to be smaller than a first dimension, a second dimension and a third dimension of container 102. Referring to FIG. 3, container 102 includes length L2, width W3 and height H2. To fit stand 302 within container 102, stand 302 may be oriented so that footwear engaging portion 306 extends along the length of container 102. Furthermore, stand 302 may be oriented so that length L1 and width W1 of stand 302 may be oriented along the width and height of container 102, respectively. In order to ensure that stand 302 fits within container 102 when container 102 is in the closed position, the dimensions of stand 302 may be selected so that length L1 is substantially less than width W3, width W1 is substantially less than height H2 and height H1 is substantially less than length L2. Moreover, the overall shape of stand 302 allows for easy insertion of footwear engaging portion 306 between first article of footwear 202 and second article of footwear 204 within container 102.

In the current embodiment, stand 302 may be configured as a wired frame. In other embodiments, however, stand 302 could be configured in any other manner. Further examples of different configurations for stand 302 are discussed later in this detailed description.

Referring back to FIG. 4, kit 100 can include steaming bag 402. In some embodiments, steaming bag 402 may comprise first peripheral edge 421, second peripheral edge 422, third peripheral edge 423 and fourth peripheral edge 424. Furthermore, steaming bag 402 may comprise central portion 404 that includes interior cavity 410. In some cases, steaming bag 402 may further comprise first peripheral portion 406 and second peripheral portion 408 that extend from central portion 404 to first peripheral edge 421 and second peripheral edge 422, respectively. First peripheral portion 406 and second peripheral portion 408 may include first end portions 436 disposed adjacent to fourth peripheral edge 424 and second end portions 438 disposed adjacent to third peripheral edge 426. In addition, third peripheral edge 423 may include peripheral opening 414 that provides access to interior cavity 410 of central portion 404. In some, but not all embodiments, fourth peripheral edge 424 may include vent 416 that provides a secondary access for central portion 404. In other words, vent 416 is an optional opening and may not be included in all embodiments.

In some embodiments, the shapes of first peripheral portion 406 and second peripheral portion 408 may vary. In some cases, first peripheral portion 406 and second peripheral portion 408 may be substantially rectangular portions or strip like portions with constant widths. In other cases, first peripheral portion 406 and second peripheral portion 408 may have variable widths. In an exemplary embodiment, for example, first end portions 436 of first peripheral portion 406 and second peripheral portion 408 may be substantially wider than second end portions 438 of first peripheral portion 406 and second peripheral portion 408. In other words, first peripheral portion 406 and second peripheral portion 408 are much larger at first end portions 436 than at second end portions 438. Moreover, this arrangement may provide central portion with a width that tapers from the widest point at third peripheral edge 423 to the narrowest point at fourth peripheral edge 424.

Steaming bag 402 may comprise a substantially elastic material that can be expanded and collapsed when filled with fluids or solid materials. In a first position, steaming bag 402 may have a substantially flat or planar geometry. Furthermore, steaming bag 402 may obtain a three dimensional geometry when filled with a solid object or fluid.

The two dimensional shape corresponding to the first position of steaming bag 402 can vary in different embodiments. In some cases, steaming bag 402 may have a substantially rectangular shape. In other cases, steaming bag 402 may have an approximately trapezoidal shape. Examples of other shapes for steaming bag 402 include, but are not limited to rounded shapes, triangular shapes, polygonal shapes, regular shapes, irregular shapes as well as any other kinds of shapes. In an exemplary embodiment, steaming bag 402 has an approximately trapezoidal shape.

In a second, or expanded, position of steaming bag 402, first side 430 and second side 432 (which is disposed opposite of first side 430) of steaming bag 402 may be separated at central portion 404. In other words, central interior cavity 410 may expand outwardly. In some cases, central portion 404 may have an approximately conical shape when expanded. In contrast to central portion 404, first peripheral portion 406 and second peripheral portion 408 may retain a substantially flattened geometry in this second position. In particular, first side 430 and second side 432 may not separate at first peripheral portion 406 and second peripheral portion 408. Instead, first side 430 and second side 434 may be fixedly attached to one another at first peripheral portion 406 and second peripheral portion 408. This arrangement allows first peripheral portion 406 and second peripheral portion 408 to be used as handles for steaming bag 402. In particular, first peripheral portion 406 and second peripheral portion 408 may retain substantially flattened geometries that may be easier to grasp than central portion 404.

The arrangement discussed here can also provide differing thermal properties for various portions of steaming bag 402. In some cases, first peripheral portion 406 and second peripheral portion 408 may have lower temperatures in a steam environment than central portion 404. This may occur as central portion 404 is filled with steam and thereby heated to a greater temperature than first peripheral portion 406 and second peripheral portion 408 which are not filled with steam.

In some embodiments, steaming bag 402 can include additional provisions for facilitating ease of use. In some cases, steaming bag 402 can include one or more holes that are easily grasped by a user. In an exemplary embodiment, steaming bag 402 can include first grasping hole 440 and second grasping hole 442 that are disposed on first peripheral portion 406 and second peripheral portion 408, respectively. In some cases, first grasping hole 440 and second grasping hole 442 may be disposed adjacent to fourth peripheral edge 424.

As seen in the Figures, container 102 comprises a convenient way of storing each of the components of kit 100. In some cases, each of the components discussed above can be packed into container 102 in the manner illustrated in FIG. 2.

Additionally, footwear engaging portion 306 can be placed or inserted between first article of footwear 202 and second article of footwear 204. Finally, steaming bag 402 can be placed in a flattened position over first article of footwear 202, second article of footwear 204 and stand 302. With this arrangement, each of the components of kit 100 may be easily stored within container 102.

A footwear customization kit may include provisions for instructing a user about how to customize an article of footwear. In the current embodiment, kit 100 can include set of instructions 500. Generally, set of instructions 500 can be supplied in any format. In some cases, set of instructions 500 may be a printed copy of instructions. For example, in one embodiment, set of instructions 500 could be provided as a booklet that is packed within container 102. In other cases, set of instructions 500 may be associated with a digital storage device. Examples of digital storage devices include, but are not limited to CD's, flash drives, memory disks as well as other types of digital storage devices. In an exemplary embodiment, set of instructions 500 may be given as a set of printed directions. Although the current embodiment illustrates set of instructions 500 as being located on interior surface 502 of lid 106, in other embodiments, set of instructions 500 could be disposed on another portion of container 102. Furthermore, in some cases, set of instructions 500 could be printed in a separate sheet and stored within container 102 rather than being affixed to a portion of container 102. In some embodiments, the instructions may be placed on portions of the device itself, for example, the instructions may be placed on steaming bag 402. In other embodiments, a notice may be placed on the device itself, for example, steaming bag 402, which informs the user to read and follow the instructions. It is possible to provide the instructions in more than one location, for example, set of instructions 500 may be both located on lid 106 and provided as a booklet packed in container 102.

Referring now to FIG. 5, set of instructions 500 may schematically illustrate the steps for customizing an article of footwear. In the current embodiment, set of instructions 500 illustrates four steps for customizing an article of footwear. First panel 510 schematically illustrates the first step, in which a stand is placed in a pot of water. Next, as illustrated in second panel 512, an article may be placed onto the stand and a steaming bag may then be placed over both the stand and the article of footwear. At this point, the water may be boiled and steam may be applied to the article of footwear including the customizable portion. Next, as illustrated in third panel 514, the bag may be removed from the article of footwear and the article may be removed from the stand. Finally, as illustrated in fourth panel 516, a user may insert a foot into the article of footwear. At this point, the customizable portion may conform to the shape of the foot as the article of footwear cools.

In some cases, set of instructions 500 can include pictures. In other cases, set of instructions 500 can include written instructions. In other cases, set of instructions 500 can include a combination of pictures and written instructions. Moreover, it will be understood that the instructions discussed and shown in FIG. 5 are only intended to be illustrative and in other embodiments additional steps can be removed or added.

FIGS. 6 through 11 illustrate an exemplary embodiment of a method of customizing article 202 using the components of kit 100. For purposes of clarity, the method is only illustrated using article 202, however it will be understood that similar steps may be repeated to customize second article of footwear 204.

Referring to FIGS. 6 and 7, stand 302, article 202 and steaming bag 402 may be associated with a steam environment. In the current embodiment, the steam environment comprises pot 600, which is filled with water 602 and further placed on burner 604. Generally, any kind of pot may be used. In some cases, a user may select a pot that is large enough to accommodate the components of kit 100. In addition, in other embodiments a user may not use a pot. Instead, a user could use any container that is capable of containing boiling water. Furthermore, in still other embodiments other types of steaming devices could be used for producing a steam environment.

As water 602 is boiled, steam can be produced for heating article 202 and specifically customizable portion 230. The components shown here can be assembled in any order. In the exemplary embodiment, stand 302 may be first placed within pot 600 and then article 202 can be placed on stand 302. As previously discussed, upper portion 312 of stand 302 may be inserted into throat opening 250 of article 202. As seen in FIG. 7, the increased width of shoulder portion 314 may help prevent article 202 from sliding all the way down footwear engaging portion 306 of stand 302.

Following this, steaming bag 402 may be placed over article 202 and portions of stand 302. As previously discussed, base portion 304 of stand 302 is configured to rest against interior lower surface 620 of pot 600. In the current embodiment, peripheral opening 414 may be placed within pot 600 towards interior lower surface 620. In an exemplary embodiment, peripheral opening 414 may cover a substantial majority of the surface area of water 602 in order to collect a majority of the steam coming from water 602. In some other embodiments, first peripheral opening 414 of steaming bag 402 can be configured to engage outer periphery 622 of pot 600 so that no steam escapes around steaming bag 402.

In some embodiments, base portion 304 of stand 302 may be disposed within water 602. In some cases, therefore, it is desirable that base portion 304 comprise a material that will withstand the high temperatures of water 602. In some cases, base portion 304 may be capable of being heated above the boiling point of water.

It is desirable that the components are assembled within pot 600 prior to water 602 boiling. Therefore, once the components of kit 100 are assembled within pot 600, a user may turn on burner 604 to heat water 602 and create a steam environment for article 202.

Referring now to FIG. 8, steam may be collected within steaming bag 402 in order to heat customizable portion 230. In some embodiments, steam may be applied for a predetermined amount of time. For example, in one embodiment set of instructions 500 (see FIG. 5) can include information about the amount of time that article 202 should be steamed. In some cases, a user could use a timer to keep track of the length of time that article 202 is exposed to steam. In other embodiments, a user may take temperature measurements inside of steaming bag 402 to determine if customizable portion 230 has been heated above a predetermined temperature. For example, in one embodiment set of instructions 500 can include information about the predetermined temperature so that a user can determine when an article has been heated to a temperature that is above the predetermined temperature. In still other embodiments, a combination of timing methods and temperature measuring methods could be used to determine when an article has been heated above a predetermined temperature.

In some cases, vent 416 may be provided to release steam from steaming bag 402. In other cases, however, no vent may be provided on fourth peripheral edge 424. In still other cases, other vents or holes could be provided at different locations on steaming bag 402.

After a predetermined period of time, steaming bag 402 may be removed from article 202 and stand 302. In some cases, a user can grasp first peripheral portion 406 and/or second peripheral portion 408 to avoid grasping central portion 404 directly. With central portion 404 filled with steam, first peripheral portion 406 and second peripheral portion 408 may have substantially lower temperatures than central portion 404. In addition, in some cases, a user may place his or her fingers through first grasping hole 440 and/or second grasping hole 442. This configuration allows a user to remove steaming bag 402 easily in a safe and effective manner.

FIGS. 9 through 11 illustrate isometric views of an embodiment of a customizable portion of an article conforming to the shape of a foot. As previously discussed, the current embodiment includes customizable portion 230 that comprises a substantial majority of upper 222 of article 202. Therefore, as a foot is inserted into upper 222, a substantial majority of upper 222 may conform to the shape of the foot.

Referring to FIG. 9, the temperature of article 202 may be above the predetermined temperature at which customizable portion 230 softens substantially. In this heated state, customizable portion 230 may be partially deformable. Initially, customizable portion 230 has a substantially smooth shape. In particular, forefoot portion 10 is generally smooth on both lateral side 16 and medial side 18 of upper 222.

Foot 900 is illustrated as inserting into article 202. In contrast to the substantially smooth shape of customizable portion 230, foot 900 has a substantially irregular shape. In this case, foot 900 includes first protrusion 902 and second protrusion 904 associated with medial side 918 and lateral side 916, respectively, of foot 900. These protrusions could be associated with any type of irregularities in the shape of foot 900 including any kinds of bony protrusions, calluses or other types of protrusions.

Referring now to FIG. 10, foot 900 has been fully inserted into upper 222. Furthermore, the temperature of article 202 is still above the predetermined temperature associated with customizable portion 230. In this heated state, customizable portion 230 may be deformed. In an exemplary embodiment, customizable portion 230 may deform so as to adapt to the shape of foot 900. Customizable portion 230 may be reshaped due the pressure applied by foot 900. For example, first contoured portion 1002 of customizable portion 230 may be formed from the local pressure applied by first protrusion 902. In other words, first contoured portion 1002 may be configured with a substantially similar geometry to first protrusion 902. In particular, first contoured portion 1002 may form a protrusion on upper 222 that corresponds to first protrusion 902 on foot 900. In a similar manner, second contoured portion 1004 of customizable portion 230 may be formed from the local pressure applied by second protrusion 904. In other words, second contoured portion 1004 may be configured with a substantially similar geometry to second protrusion 904. In particular, second contoured portion 1004 may form a protrusion on upper 222 that corresponds to second protrusion 904 on foot 900.

It should be understood that a customizable portion could adapt to any geometric features of a foot. In some cases, the customizable portion may adapt to protrusions of various kinds. Additionally a customizable portion can adapt to the overall shape and geometry of a foot. For example, in an embodiment where a user has relatively wide arch, a customizable portion comprising a portion of the upper may be configured to expand at the arch to provide a better fit for the user. In other words, a customizable portion can be deformed to accommodate global geometric features of a foot in addition to local geometric features such as protrusions.

In order to ensure that customizable portion 230 is substantially permanently deformed in a manner that corresponds to foot 900, it is desirable that article 202 cool below the predetermined temperature before removing foot 900. In some cases, a user could make a temperature measurement of article 202. In other cases, a user may wait a predetermined period of time before removing article 202 to ensure that article 202 has sufficiently cooled. In some embodiments, a set of instructions could provide information for a user including a desired amount of time for keeping a foot inserted inside an article of footwear.

After article 202 has cooled below the predetermined temperature, foot 900 can be removed from upper 222, as illustrated in FIG. 11. Customizable portion 230 may substantially retain the shape corresponding to foot 900 following the removal of foot 900. In this case, customizable portion 230 retains first contoured portion 1002 and second contoured portion 1004 even after foot 900 as been removed. With this arrangement, upper 222 may be substantially permanently reshaped to provide a better fit and enhanced comfort for the user.

In some embodiments, the process of reshaping a customizable portion may only occur once over the lifetime of an article. In some cases, for example, a customizable portion may be made of a material that can only be cured a single time. In other words, the cycle of heating the customizable portion above a predetermined temperature, deforming the customizable portion and then cooling the customizable portion below the predetermined temperature can only occur once. Such materials may not return to a substantially deformable state after being reheated above the predetermined temperature. In other embodiments, however, the process of reshaping a customizable portion could occur two or more times over the lifetime of an article.

FIGS. 12 through 16 illustrate alternative embodiments of stands that may be used with a footwear customization kit. It will be understood that the examples of stands given here are not intended to be limiting and in other embodiments still other kinds of stands can be used with a footwear customization kit.

In the current embodiment, base portion 1204 may have an approximately oval-like or elliptic shape. In addition, footwear engaging portion 1206 may have an approximately two dimensional shape that extends from base potion 1204 in a perpendicular manner. Examples of different shapes for footwear engaging portion 1206 include, but are not limited to any of the shapes discussed above for base portion 1204. In an exemplary embodiment, footwear engaging portion 1206 may have an irregular shape.

In some cases, footwear engaging portion 1206 can comprise distinct portions that are associated with different portions of an article of footwear. In some embodiments, footwear engaging portion 1206 may include lower portion 1210 and upper portion 1212. Lower portion 1210 may be disposed adjacent to base portion 1204. In some cases, lower portion 1210 may have a substantially larger width than upper portion 1212. In particular, upper portion 1212 may be narrow enough to insert into a throat opening of an article. In contrast, lower portion 1210 may be substantially wider than upper portion 1212. In particular, lower portion 1210 may be wider than the throat opening of an upper. In some cases, footwear engaging portion 1206 can also include shoulder portion 1214 that extends between lower portion 1210 and upper portion 1212. In one embodiment, the width of shoulder portion 1214 may vary between lower portion 1210 and upper portion 1212. With this arrangement, the throat opening of an article may rest against shoulder portion 1214 to help hold an article in place and in a generally upright position.

In some embodiments, footwear engaging portion 1206 may further comprise intermediate portion 1215 that is disposed between first end potion 1207 and second end portion 1208. In some cases, intermediate portion 1215 may be disposed within lower portion 1210. In other cases, intermediate portion 1215 could be disposed within upper portion 1212. In an exemplary embodiment, intermediate portion 1215 may be disposed within lower portion 1210.

Intermediate portion 1215 may comprise first cross bar 1216 and second cross bar 1218. First cross bar 1216 may extend across lower portion 1210 in a generally widthwise direction. In other words, first cross bar 1216 may extend from lateral side 1286 to medial side 1288 of stand 1202. Similarly, second cross bar 1218 may extend from lateral side 1286 to medial side 1288 of lower portion 1210. In some cases, first cross bar 1216 and second cross bar 1218 can comprise substantially rounded cross sectional shapes. In other cases, however, first cross bar 1216 and second cross bar 1218 may have any other kinds of cross sectional shapes.

In some embodiments, first cross bar 1216 and second cross bar 1218 may provide enhanced strength for stand 1202. In addition, in some cases, first cross bar 1216 and second cross bar 1218 may provide means for attaching a detachable portion to stand 1202, as discussed in further detail below.

In some embodiments, a stand can include provisions for protecting the laces of an article. In some cases, a stand can include features to prevent the laces of an article from hanging down below the heel portion of the article. For example, in embodiments where an article may be placed within a pot of boiling water, a stand can include provisions for preventing the laces from contacting the boiling water directly. In one embodiment, a stand can include a detachable portion that can be used to secure the laces above the boiling water.

In the current embodiment, stand 1202 may include detachable portion 1220. Detachable portion 1220 may include lace receiving portion 1222 and peripheral portion 1224. Peripheral portion 1224 may extend around lace receiving portion 1222.

In some cases, lace receiving portion 1222 may include plurality of holes 1240 that allow steam to pass through detachable portion 1220. However, it will be understood that in other embodiments other provisions could be used including slots, meshes or any other provisions that allow steam to pass through portions of detachable portion 1220. Moreover, in other embodiments detachable portion 1220 may not include any holes, slots or meshes.

Generally, the geometry of detachable portion 1220 can vary. Examples of different shapes for detachable portion 1220 include, but are not limited to, rounded shapes, rectangular shapes, polygonal shapes, regular shapes, irregular shapes as well as any other kind of shapes.

In other cases, however, stands including folding portions could be made of any other kind of material.

An article of footwear can be provided with two or more distinct materials that can be deformed when heated above a predetermined temperature and then retain differing rigidities when cooled below the predetermined temperature. For example, in one embodiment, an upper may comprise a first material that is customizable and an insert may comprise a second material that is customizable. Moreover, the second material may be substantially more rigid than the first material after both materials are heated above a predetermined temperature and then cooled again. In another embodiment, an upper may comprise a first material that is customizable and a sole structure may comprise a second material that is customizable. Moreover, the first material and the second material may have substantially different rigidities after both materials are heated above a predetermined temperature and then cooled again. Still further, in other embodiments, three or more customizable materials could be used for different portions of an article of footwear.

FIGS. 17 through 21 illustrate another embodiment of a customization system for customizing an article of footwear. Referring to FIGS. 17 and 18, customization kit 1700 includes first article of footwear 1802, second article of footwear 1804, stand 1702 and steaming bag 1704. Kit 1700 further includes container 1706 for storing each of these components. These components are substantially similar to the components discussed in the previous embodiments. Kit 1700 may also include a set of optional customizable inserts. In this case, kit 1700 includes first customizable insert 1710 and second customizable insert 1712. First customizable insert 1710 and second customizable insert 1712 may be used with first article of footwear 1802 and second article of footwear 1804, respectively.

Although the current embodiment illustrates removable inserts, in other cases other types of inserts could be used. For example, in another embodiment, an insert could be embedded or integrally formed with an article of footwear. In one embodiment, an insert could be integrally formed with an interior portion of an upper. In another embodiment, an insert could be integrally formed with an interior surface of a sole structure. In still other embodiments, an insert could be embedded or integrally formed with any other component of an article of footwear.

For purposes of clarity, only first customizable insert 1710 is discussed in detail, however it should be understood that the same principles may apply to second customizable insert 1712 that is configured to be used with second article of footwear 1804. Furthermore, throughout the remainder of this detailed description first article of footwear 1802 and first customizable insert 1710 may be referred to as article 1802 and customizable insert 1710, respectively.

Article 1802 may be substantially similar to article 202 discussed in the previous embodiments. Article 1802 may comprise upper 1822 and sole structure 1824. For purposes of locating different features of article 1802, article 1802 may be associated with forefoot portion 10, midfoot portion 12 and heel portion 14 as well as with lateral side 16 and medial side 18.

In some embodiments, upper 1822 may be associated with one or more customizable portions. In some cases, a customizable portion may be associated with forefoot portion 10, midfoot portion 12 and/or heel portion 14 of upper 1822. In other cases, a customizable portion may be associated with any combination of different portions of upper 1822. In an exemplary embodiment, upper 1822 may include customizable portion 1830. In particular, customizable portion 1830 may extend through a substantial majority of upper 1822. In some cases, customizable portion 1830 may coincide with upper 1822.

The characteristics of customizable portions can be varied in different ways. In some embodiments, a customizable portion can be varied through a curing process. In other words, the customizable portion may be heated above a predetermined temperature and modified before cooling the customizable portion so that the modifications are retained. In other embodiments, the characteristics of customizable portions can be varied through the use of pressure, chemical additives or other known methods of changing the characteristics of material including the size, shape, rigidity, flexibility and/or other properties. In still other embodiments, a combination of heat, pressure and/or chemicals could be used to modify the customizable portion.

In order to modify customizable portion 1830, article 1802 may be heated above a predetermined temperature. In some cases, article 1802 may be placed in an oven. In other cases, article 1802 may be heated using steam. In an exemplary embodiment, article 1802 may be heated in any steam environment. A steam environment can be created in different ways. In some cases, a steam environment can be created using a pot with water that may be boiled to create steam. In other cases, any other devices or mechanisms for creating steam can be used.

In different embodiments, customizable insert 1710 can be associated with different portions of article 1802. In some cases, customizable insert 1710 may be associated with forefoot portion 10. In other cases, customizable insert 1710 may be associated with midfoot portion 12. In still other cases, customizable insert 1710 may be associated with heel portion 14. In an exemplary embodiment, customizable insert 1710 may be configured as a heel insert that is associated with heel portion 14 of article 1802. In some cases, customizable insert 1710 may be removably inserted from article 1802 through throat opening 1828.

Customizable insert 1710 may comprise base portion 1720 and sidewall portion 1722. Sidewall portion 1722 may be disposed at an angle with respect to base portion 1720. In some cases, sidewall portion 1722 may be configured to contact the sides and rear of a heel. Likewise, base portion 1720 may be configured to receive the bottom surface of a heel.

In some embodiments, customizable insert 1710 may be customized using heat. In some cases, the shape of customizable insert 1710 may be changed by raising the temperature of customizable insert 1710 above a predetermined temperature. In one embodiment, the shape of customizable insert 1710 may be changed by applying steam to customizable insert 1710.

In some embodiments, the material properties of customizable portion 1830 and customizable insert 1710 may vary. In some cases, customizable portion 1830 and customizable insert 1710 may be made of substantially similar materials. In other cases, customizable portion 1830 and customizable insert 1710 may be made of substantially different materials. In an exemplary embodiment, customizable portion 1830 and customizable insert 1710 may be made of substantially different materials.

As previously discussed, customizable portions can be made from any known materials or combination of materials. Examples of materials that may be used include, but are not limited to: any kind of thermoplastics, thermoset polymers, thermoset resins (such as epoxy, vinlyester and polyster), synthetic leathers including poromeric leathers and lorica, as well as any other kinds of materials with customizable characteristics. In an exemplary embodiment, a customizable portion may be constructed as a synthetic leather comprising two polymer layers that sandwich a canvas sheet. Moreover, a glue used to bond the polymer layers to the canvas may be configured with a relatively low melting point. When steamed, this glue can stretch or shrink to accommodate a customized shape. Although the current embodiment discusses a three-layered construction, other customizable portions could incorporate any other number of layers including a single layer construction.

Customizable inserts can be made of any known materials or combinations of materials. Examples of materials that may be used for a customizable insert include, but are not limited to: any kind of thermoset polymers, thermoset resins (such as epoxy, vinylester and polyester), synthetic leathers, as well as any other materials with customizable characteristics. In some embodiments, a customizable insert can be made from a thermoset foam. In one embodiment, a customizable insert can be made of a modified ethyl-vinyl-acetate (EVA) material that has thermoset properties.

In some embodiments, materials for a customizable portion of an article and a customizable insert can be selected according to material characteristics such as durability, rigidity and/or flexibility. In an exemplary embodiment, materials for a customizable portion that is used with an upper and a customizable insert may be selected so that the customizable portion is substantially less rigid than the customizable insert after curing. This arrangement may allow for a greater degree of flexibility for the customizable portion as the foot moves. In contrast, the customizable insert may be relatively rigid after curing to ensure good support for a heel during use.

Referring now to FIG. 18, the components of kit 1700 may be assembled within a steam environment in order to customize article 1802. In the current embodiment, pot 1850 and burner 1852 are used to boil water 1854 for creating steam. Furthermore, article 1802 has been placed on stand 1702 within pot 1850. Steaming bag 1704 has been placed over stand 1702 and article 1802 to capture the steam. With this arrangement, both customizable portion 1830 of upper 1822 and customizable insert 1710 may be heated above the predetermined temperature.

In this exemplary embodiment, article 1802 is held in a substantially vertical position. In other words, heel portion 14 is substantially closed to water 1854 than forefoot portion 10. In some cases, this arrangement can help ensure that customizable insert 1710 is heated above the predetermined temperature.

FIGS. 19 through 21 illustrate isometric views of an embodiment of a customizable portion of an article and a customizable insert simultaneously conforming to the shape of a foot. As previously discussed, the current embodiment includes customizable portion 1830 that comprises a substantial majority of upper 1822 of article 1802. Therefore, as a foot is inserted into upper 1822, a substantial majority of upper 1822 may conform to the shape of the foot. Additionally, article 1802 includes customizable insert 1710 that can be customized to the shape of a heel.

Referring to FIG. 19, the temperature of article 1802 may be above the predetermined temperature at which customizable portion 1830 softens substantially. In this heated state, customizable portion 1830 may be partially deformable. Initially, customizable portion 1830 has a substantially smooth shape. In particular, forefoot portion 10 is generally smooth on both lateral side 16 and medial side 18 of upper 1822.

Foot 1900 is illustrated as inserting into article 1802. In contrast to the substantially smooth shape of customizable portion 1830, foot 1900 has a substantially irregular shape. In this case, foot 1900 includes first protrusion 1902 and second protrusion 1904 associated with medial side 1918 and lateral side 1916, respectively, of foot 1900. These protrusions could be associated with any type of irregularities in the shape of foot 1900 including any kinds of bony protrusions, calluses or other types of protrusions.

The temperature of customizable insert 1710 may also be above the predetermined temperature at which customizable insert 1710 softens substantially. Initially, customizable insert 1710 has a substantially smooth shape. In particular, base portion 1720 has a substantially constant thickness. Also, sidewall portion 1722 has a substantially constant height. It will be understood that in some cases, customizable insert 1710 and customizable portion 1830 may be associated with substantially similar predetermined temperatures or glass transition temperatures. However, in other cases, customizable insert 1710 and customizable portion 1830 may be associated with substantially different predetermined temperatures. In such cases, as long as the steam environment is able to raise the temperature of article 1802 above both predetermined temperatures, customizable insert 1710 and customizable portion 1810 may both be cured during a single process.

Referring now to FIG. 20, foot 1900 has been fully inserted into upper 1822. Furthermore, the temperature of article 1802 is still above the predetermined temperature associated with customizable portion 1830. In this heated state, customizable portion 1830 may be deformed. In an exemplary embodiment, customizable portion 1830 may deform so as to adapt to the shape of foot 1900. Specifically, in this case, customizable portion 1830 may be reshaped due the pressure applied by foot 1900. For example, first contoured portion 2002 of customizable portion 1930 may be formed from the local pressure applied by first protrusion 1902. In other words, first contoured portion 2002 may be configured with a substantially similar geometry to first protrusion 1902. In particular, first contoured portion 2002 may form a protrusion on upper 1822 that corresponds to first protrusion 1902 on foot 900. In a similar manner, second contoured portion 2004 of customizable portion 1830 may be formed from the local pressure applied by second protrusion 1904. In other words, second contoured portion 2004 may be configured with a substantially similar geometry to second protrusion 1904. In particular, second contoured portion 2004 may form a protrusion on upper 1822 that corresponds to second protrusion 1904 on foot 1900.

It should be understood that a customizable portion could adapt to any geometric features of a foot. In some cases, the customizable portion may adapt to protrusions of various kinds. Additionally a customizable portion can adapt to the overall shape and geometry of a foot. For example, in an embodiment where a user has relatively wide arch, a customizable portion comprising a portion of the upper may be configured to expand at the arch to provide a better fit for the user. In other words, a customizable portion can deformed to accommodate global geometric features of a foot in addition to local geometric features such as protrusions.

Also, with foot 1900 fully inserted into upper 1822, customizable insert 1710 may adapt to the shape of foot 1900. In some cases, base portion 1720 may be deformed under the weight of heel 1910 (see FIG. 21). In particular, base portion 1720 may be compressed so that the thickness of base portion 1720 varies in a widthwise direction. Also, sidewall portion 1722 may conform to the shape of the side portions and rear portions of heel 1910. It will be understood that the variations in the geometry of customizable insert 1710 illustrated and discussed in this embodiment are only intended to be exemplary. In other embodiments, any other kinds of deformations are possible. In particular, both global geometric properties and local geometric properties of customizable insert 1710 could be varied.

In order to ensure that customizable portion 1830 and customizable insert 1710 are substantially permanently deformed in a manner that corresponds to foot 1900, it is desirable that article 1802 cool below the predetermined temperature before removing foot 1900. In some cases, a user could make a temperature measurement of article 1802. In other cases, a user may wait a predetermined period of time before removing article 1802 to ensure that article 1802 has sufficiently cooled. In some embodiments, a set of instructions could provide information for a user including a desired amount of time for keeping a foot inserted inside an article of footwear.

After article 1802 has cooled below the predetermined temperature, foot 1900 can be removed from upper 1822, as illustrated in FIG. 21. Customizable portion 1830 may substantially retain the shape corresponding to foot 1900 following the removal of foot 1900. In this case, customizable portion 1830 retains first contoured portion 2002 and second contoured portion 2004 even after foot 1900 as been removed. With this arrangement, upper 1822 may be substantially permanently reshaped to provide a better fit and enhanced comfort for the user. In a similar manner, customizable insert 1710 may also substantially retain the shape corresponding to heel portion 1910 of foot 1900.

Furthermore, after cooling, customizable portion 1830 and customizable insert 1710 may acquire substantially different rigidities. In some cases, customizable portion 1830 may be substantially less rigid that customizable insert 1710. This arrangement allows customizable portion 1830, which comprises a substantial majority of upper 1822, to flex and accommodate movement of a foot during use. In contrast, customizable insert 1710 may be relatively rigid to increase support for a heel.
